A nice 1942 dated Enfield Revolver by Albion Motors. The
brass marking disc on the grips is also marked Albion Motors

The vast majority of Enfield No 2 revolvers were made by RSAF (Royal Small
Arms Factory) Enfield, but wartime necessities meant that numbers were
produced elsewhere. Albion Motors in Scotland made the Enfield No 2 Mk
I* from 1941 to 1943, whereupon the contract for production was passed
onto Coventry Gauge & Tool Co. By 1945, 24,000 Enfield No 2 Mk I*
and Mk I** revolvers had been produced by Albion/CG&T. The Singer
Sewing Machine Company of Clydebank made components but they were assembled
at Enfield under their proofmarks; Singer-made parts are marked "SSM".
